Fast Food Point of Sale (POS) System

You have been hired to create the point of sale (POS) system for a new fast food restaurant. The restaurant has a limited menu -- Hamburgers, Chicken Sandwiches, and Fish Sandwiches. Each may be purchased separately or as part of a Combo that includes fries and a drink. Combos may be Supersized to include a larger order of fries and an extra large drink. The table below gives the price for each type of order:

Meal Sandwich Combo Supersize
Hamburger $ 2.50 $ 4.50 $ 5.00
Chicken Sandwich $ 3.00 $ 5.00 $ 5.50
Fish Sandwich $ 2.75 $ 4.75 $ 5.25

Requirements

You will write a program named FastFoodPOS.
It must display a header that lists the name of the application -- you may name the application as you like -- and provides instructions about using the program. For example,


Welcome to Wolfpack Fast Food POS!
When prompted, please enter the number of meals to be purchased, the type
of each meal -- H (Hamburger), C (Chicken Sandwich), or F (Fish Sandwich) -- and
whether or not it is a Combo. If it is a Combo, you will be prompted as to whether
or not it should be Supersize. The total cost of the meals will then be displayed.


The user should be prompted for the following input values:

The number of meals to purchase. For each meal the user should be prompted for
The meal type (H, C, F). Both uppercase and lowercase characters should be accepted.
If the meal is a Combo (y, n). A yes answer should be assumed if the user enters anything that starts with y or Y. Any other response is considered to be a no answer. If the meal is a Combo, the user should be prompted for
If the Combo should be Supersize (y, n). A yes answer should be assumed if the user enters anything that starts with y or Y. Any other response is considered to be a no answer.

The program should then output the total cost of the meals formatted as a monetary amount, for example, $12.25.
